History Of The Gas Mask: How Need Brought Us The Weirdest-Looking Common Tool
The gas mask has come to be an international symbol of wartime atrocities, but it began as a tool for people tasked with unenviable and dangerous jobs. Long before chlorine gas filled the trenches of World War I, a fairly simple invention helped people breathe through strenuous activities, whether it underwater diving or coal mining. Although the initial versions of gas masks were created to make life easier for regular people, they went on to (literally) change the face of the military.
Made For Firefighters
In the 19th century, more than one intrepid inventor recognized the potential market for devices to filter gas, dust, and muck from the air. Many jobs of the day, and today as well, were hazardous for the lungs of the people doing them: firefighters, divers, coal miners, etc. If they had masks, maybe they'd stop dropping dead so often, or at least be a little more comfortable.
John and Charles Deane patented a "standard dress" helmet for firemen to wear while entering smoke-filled rooms in 1823. It wasn't perfect—a giant helmet wasn’t really a feasible way for firemen to get around—but it was better than nothing. In 1827, they modified the helmet to help divers breathe underwater.
